What else can I help you with?
Can you explain the difference between physical changes and chemical changes?
Physical changes is change in property. Ex) change from solid to liquid....ice to water. Chemical change changes to different substances. Ex) rotting of fruit.
Is wood rotting a chemical change or physical change?
it is a chemical reaction because a new substance is formed when the wood rots
Is etching glass with acid a chemical or physical change?
It is a physical change caused by chemicals. Chemical changes are phyiscal changes.
Gasoline is an example of energy released by blank changes?
The coubustion of gasoline is an example of energy released by chemical changes
Two changes that are harmful?
Physical and chemical changes are harmful to us.
Polymers are formed by hydrolysis?
Polymers are typically formed by condensation reactions, not hydrolysis. In a condensation reaction, monomers combine to form a polymer chain with the release of a small molecule like water. Hydrolysis, on the other hand, is the breakdown of polymers into monomers by the addition of water molecules.
Macromolecule formed when monomers are joined together?
A polymer is formed when monomers are joined together through chemical bonds. Polymeric macromolecules can have a wide range of functions and properties depending on the specific monomer units and how they are linked. Examples of polymers in nature include proteins, DNA, and carbohydrates.
If a substance changes its color and gives off a gas when heated is it a compound?
Yes, if a substance changes its color and gives off a gas when heated, it is likely a compound undergoing a chemical reaction. The change in color and evolution of gas suggest that new substances are being formed through chemical bonds breaking and forming.
What changes shape in a chemical reactions?
New molecules are formed.
Why do we us molecules in our body?
All life be it animal or vegetable is formed of organic molecules. Humans can be thought of as 'electro-chemical polymers'.
When a physical changes occurs a substance's changes?
A new substance is formed only after a chemical change.
Can you name two chemical changes?
Two examples of chemical changes are the rusting of iron and the combustion of gasoline. In chemical changes, new substances are formed due to the rearrangement of atoms.
What are polymers containing up to 20 different kinds of?
Polymers are formed from monomers.
What type of chemical reaction connects polymers together?
The type of chemical reaction that connects polymers together is dehydration synthesis.
When polymers chemically bond with other polymers this is called?
When covalent bonds are formed between polymers, this is called cross-linking
Polymers are formed by hydrolysis true or false?
This is for sure &*!@)!(@)!(@, this is because senior is too good for you.
What are the similarities between chemical and physical changes?
Both chemical and physical changes involve a transformation of matter. In physical changes, the substance's chemical composition remains the same, while in chemical changes, new substances are formed as a result of a chemical reaction. Both types of changes involve the absorption or release of energy.
